[comp.unix.microport] AST 4-port under uport /386 v 3.0-2.2L

keld@freja.dk (Keld J|rn Simonsen) (08/19/88)

I have problems installing an AST 4-port card on an NCR PC 916
machine running Microport UNIX/386 release 3.0 2.2L
My UNIX/386 includes DOS/MERGE and an Everex tape driver.
It is a 2-user license.

My problem is, that I can get the UNIX to read characters from 
the card, at least from the first port, but I cannot write
thru the board to the terminal.

I have installed the card as specified, in enhanced mode
and with IRQ 3 enabled. I have removed all other cards
which could use IRQ 3, including my second serial/parallel
port and my tape controller.

I have used ttypatch as specified in the manual with the options:

ttypatch -t01 -i3 -n4 -a416 -v447 -m0

The board is set to be the first address. I get the lines on
the tty interface up, pin 4,5,6,8 and 20 is high, when I open the
interface. I have tried both cu and opening it with cat -u.
When I address tty04 the system panics.

Can anybody help me please!

I had a similiar problem with a Computone Intelliport, Microport L2.2 and
Locus Merge 1.0 and the Everex tape driver. Had to acquire a Microport
specific driver from Computone, a version of Locus Merge386 called 1.0a
which only included files sufficient to replace atconf --- but then the
fun began.

I also had a problem, but it turned out to be an option switch
setting.  Specifically, if the AST's "Interrupt Sharing" switch is
enabled (SW3-3 down), the AST board is then looking for *another*
AST board to be installed in your computer.  If it doesn't find it,
things tend to just sit there.  Turning the switch ON (disable
interrupt sharing) made everything work just just fine.

On my system, I have a multi-purpose board on IRQ4 (parallel
printer and serial port /dev/tty0), so I set up the AST for IRQ3.
Here are the specifics...(I saved it in /etc/ttysetup just so I could
always do it the same way again when the next system upgrade comes
through):

----/etc/ttysetup--------------
  #  Setup for AST 4-port Cluster board
  #
  #  NOTE: AST Interrupt sharing switch is set to "disabled" (SW3-3 ON)
  #   tty1 (IRQ 3 == COM2) is not connected
  #
  #  IRQ     3
  #  Vector  447 (0x1bf)
  #  Channel 1   416-423 (0x1a0-0x1a7) tty2
  #  Channel 2   424-431 (0x1a8-0x1af) tty3
  #  Channel 3   432-439 (0x1b0-0x1b7) tty4
  #  Channel 4   440-446 (0x1b8-0x1be) tty5
  #
  /etc/ttypatch -t2 -n4 -i3 -v447 -a416  -m0
  
  #  IRQ    4   1016-1023 (0x3f8-0x3ff) tty0
  #
  /etc/ttypatch -t0 -n1 -i4       -a1016 -m12
  
  #  No tty1 defined
  #
  /etc/ttypatch -t1 -n1 -c
